Charles Phillips, President, Oracle
An actress was almost the undoing of Charles Phillips, president of Oracle.
Phillips in January acknowledged an 8-year extramarital affair after his jilted mistress plastered several cities with billboards calling attention to their relationship.
That mistress, YaVaughnie Wilkins, was angry over Phillips' decision to reconcile with his wife, and hired contractors to erect billboards in several cities showing photos of her and Phillips together. She also released photo of the two together taken over the course of their affair.
While billboards showing Phillips and Wilkins were quickly pulled down and Wilkins' Website where she posted the photos is no longer active, the Daily Mail still maintains photos of those billboards and other photos of the two together.
Phillips, unlike the other executives in this list, managed to avoid retiring or being fired in the wake of the scandal.
